Has anyone seem this? Anyone know what fuel they loaded for such tests?
-
:airplane: The "standard" fuel load for the "D" model, after a visit to "IRAN", (inspection, repair as necessary), was 40 gallon in left and right main. Was told that was the standard loadout for a factory test flight after production, therefore it was carried over to test flights after IRAN. Can't be positive because of the different dash number engines, but I would venture a guess that it was probably the same.

Interesting. Seems that our P51 cannot make the trials to be accepted then.

Where do you see a discrepancy?
(Not saying there isn't one, I just don't know the in-game bird well enough to pick it out on paper)

If you read carefully,you'll see most of the test shown are done with 150 Octane fuel at 72 inch MAP!
Niether of our ponies will meet those speeds or climb because we use 100 Octane fuel and 67 in of MAP.

Thought it was 130oct 67Hg.

Bustr,I beleive we are both correct it would be 100/130,I guess I should have stated that.

The 1st 2nd and 3rd tests were run using ordinary 100/130 grade fuel or AN-F-28 to a maximum boost of 67 in Hg, although early tests showed 60.5 in Hg ( http://www.wwiiaircraftperformance.org/mustang/V-1650-3-low-blower-curve.jpg )
4th to 7th were run using 104/150 grade or 44-L and boosts of 72 or 75 in Hg (eg: http://www.wwiiaircraftperformance.org/mustang/na-p51b-150grade-level.jpg )
The 8th test "Flight Test Engineering Branch, Wright Field, Dayton, Ohio 15 June 1945: Flight Tests on the North American P-51D Airplane, AAF No. 44-15342" is again using standard 100/130 grade fuel and maximum boost of 67 in Hg.

This is why I said MOST and not all,however I hadnt noticed that the last test was done on 100/130,guess I should have looked more closely. I had assumed tests 4 through 8 were all on 150.

Tests are one thing.... What was available in the European Theater after April 44 for the 8th and 9th AF?
PPF,

It must be the fuel difference. The time to climb is off - I thought it might be due to the fuel load we use in the MA.
I really want the higher octane fuel. Of course then I also want other things that would get me shot for saying so around here :bolt:
-
150 avgas could be made available as a perk option for the late-war allied planes. C3 perk fuel for the 109K would also be nice. Quality fuel for the Nippon rides too...

While I would happily pay a perk price to have 150 octane in the Mossie, AH just isn't set up to do different flight models off of one selection in the hangar. We'd need a perk listing for each aircraft as well as the current free listing.
Quality fuel for the Nippon rides too...
Unfortunately for the game, but fortunately in reality, the Japanese simply didn't have better fuel. Calling it 87 octane is almost certainly generous.
-
Yeah, but we know that their engines were made to take advantage of better fuels if it became available. As a perk option I think it would be nice to include a few "what ifs" in the MA. Any and all perk options should of course be possible to disable for scenarios. As for how the game handles perks options, that can be changed; all the data should be loaded into variables anyway, so a simple drop down menu should be enough to change which FM is loaded into the variables. I hope to one day see a more usable perk system were we get to chose engine options (fuel quality, ADI, NOS etc.), loadout options including perked "experimental" loadouts and "what ifs". Things that were tested, but didn't make it into (full) production for some reason or another.

150 was first available at Group level in June 44 for ETO.
Most of the Flight Tests on Williams' site have full internal wing fuel (194 gallons) and the test document will state 'full combat load or equivalent with ballast to include full ammo load. They will all state whether the fuse tank was full - but most tests were conducted without the 85 gallons in the Fuse tank for P-51B-7 and above all the way through the P-51D-15.
One of the flight tests has a full range of cruise with 75/110 gallon tanks as well as 500 pound bombs - at different throttle/rpm vs altitude

I agree - the higher octane would be nice as a perk option.

I disagree. I have a pretty good idea of what an AH airplane can and can not do. This absolutely will effect how I engage and fly against my opponent. Giving a player an option to essentially upgrade their plane to a super version throws that out the window as I would have no idea which version they are flying.

Likewise, you can't know for sure the quality of the pilot you encounter either. I think that some variability introduces new unknowns, making for a greater challenge. I like the idea of perked fuel. Especially since every most, if not all, ETO Allied fighters were flying with 150 octane fuel by the fall of 1944.

Wide, we already have that because of icons. A F4U-1 is a big difference from a dash four.

The icon can't tell you what fuel the aircraft is using... A P-51D using 150 fuel gets a considerable performance boost in acceleration and climb, and Spitfires get a significant boost as well. The possibility of encountering these with 150 octane fuel will add a certain level of uncertainty that I view as a good thing.
-
All I was saying is with the disparity in some birds, you already have some uncertainty. I think it it an excellent thing myself as well - plus the bulk of the war seems that the Pony was a beast unstead of castrated as we have in game.
-
well the icon could show it..
-
Funny y'all are talking about AVGAS octane. My job for Chevron is texting octane on gas for cars and prop planes. Our AVGAS is typically in the 134 octane range. The engine that I perform the test on was classified during WW2.
-
Instead of stars for achievements, I am thinking drums of 150 Avgas in lieu of lower octane ............ :D
